What is Azure App Service?
Azure App Service is an HTTP-based service for hosting web applications, REST APIs, and mobile back ends. You can develop in your favorite language, be it .NET, .NET Core, Java, Node.js, PHP, Python, or Ruby. You can also run PowerShell and other scripts or executables as background services. Applications run and scale with ease on both Windows and Linux-based environments.
Azure App Service adds the power of Microsoft Azure to your application, such as security, load balancing, autoscaling, and automated management. Additionally, you can take advantage of its DevOps capabilities, such as continuous deployment from Azure DevOps, GitHub, Docker Hub, and other sources, package management, staging environments, custom domain, and TLS/SSL certificates.
With Azure App Service, you pay for the Azure compute resources you use. The compute resources you use are determined by the App Service plan that you run your apps on. For more information, see .

FAQs
Here are some frequently asked questions about Azure App Service:
What is the difference between Azure App Service and Azure Functions?
Azure App Service and Azure Functions are both PaaS offerings for hosting web apps and APIs on the cloud. However, they have different models and use cases. Azure App Service is based on the app service plan model, where you pay for the compute resources you use based on the size and number of instances. Azure Functions is based on the consumption plan model, where you pay for the number of executions and memory usage of your functions. Azure Functions is ideal for event-driven or serverless scenarios, where you need to run small pieces of code in response to triggers or events. Azure App Service is ideal for web or mobile scenarios, where you need to run full-fledged web apps or APIs with more control and flexibility.
How can I access the Kudu console for my app?
The Kudu console is a web-based tool that provides advanced management and troubleshooting capabilities for your app. You can access the Kudu console by appending .scm.azurewebsites.net to your app's URL. For example, if your app's URL is myapp.azurewebsites.net, then the Kudu console's URL is myapp.scm.azurewebsites.net. You can also access the Kudu console from the Azure portal by selecting your app and clicking on Advanced Tools.
